Grundfos JP6 Capacitor
The Grundfos JP6 is a 1.06 kW single-phase jet pressure pump commonly found in well & domestic pumps setups. Its motor runs on a 25µF 450V motor-run capacitor in a CBB60-style can — here's the exact replacement and how to confirm it.

Manufacturer-documented25µF · 450V
The Grundfos JP6 jet pressure pump uses a 25µF 450V motor-run capacitor (CBB60-style) — it's the part that helps the single-phase motor start and keep running smoothly. We source this value from manufacturer / supplier documentation. Match the replacement to 25µF (about 22.5–27.5µF) at 450V or higher; the checklist below covers how to confirm it against your own capacitor.
The capacitor that fits
One listing covers every terminal style — open it and choose your terminal (lug, flying lead, or stud) from the dropdown to match how your old capacitor's wires come out. Not sure? Any works electrically; the terminal is just the connection.
How to be sure you get the right one
- µF must match — the JP6 needs 25µF (about 22.5–27.5µF), within roughly ±5–10%. Too low and the motor won't start; too high and it runs hot.
- Voltage can go up, never down — a 450V (or higher) cap is correct here; a 450V part safely replaces a 370V or 440V one. Don't fit below 450V.
- Check the terminal + size — make sure the new cap physically fits the housing and the connections match (the JP6 typically uses a flying-lead terminal).
- When in doubt, read your old cap — the printed µF and voltage on the part you're replacing is the final word.
Common questions — Grundfos JP6 capacitor
What capacitor does the Grundfos JP6 use?
A 25µF 450V motor-run capacitor (CBB60-style). Always confirm against the rating printed on your existing capacitor before ordering.
Can I fit a higher-voltage capacitor in the Grundfos JP6?
Yes — voltage can be equal or higher, never lower. A capacitor rated 450V or above is fine (450V is the usual choice), as long as the µF still matches (25µF).
